Step-by-step explanation:
Perimeter of the triangle ABC is 18.7 units.
Coordinate of the point A is (4, -1), B is (-1, 4) and C is (0, -3).
Length of the side AB = 
AB = 
AB = 7.07 units = 7.1 units ( rounded to the nearest 10th)
Length of the side BC = 
BC = 
BC = 
BC = 7.07 units = 7.1 units ( rounded to the nearest 10th)
Length of the side CA =
CA = 
CA = 
CA = 4.47 units = 4.5 ( rounded to the nearest 10th)
Perimeter of the triangle ABC = sum of all three sides = (7.1 + 7.1 + 4.5) units = 18.7 units
